Final answer:
The divisions of class 3 hazardous materials include listed, characteristic, and mixed wastes.
Step-by-step explanation:
The divisions of class 3 hazardous materials are based on their characteristics. The Environmental Protection Agency (EPA) categorizes hazardous wastes into three divisions: listed, characteristic, and mixed wastes.
Listed hazardous wastes are materials specifically listed as hazardous wastes, which can come from non-specific sources, specific sources, or discarded chemical products. The EPA provides four lists (the F, K, P, and U lists) of hazardous materials.
Characteristic hazardous wastes are materials that are dangerous because they exhibit properties such as ignitability, corrosivity, reactivity, or toxicity.
Mixed wastes are wastes that have both hazardous and radioactive components and are regulated under both the Resource Conservation and Recovery Act (RCRA) and the Atomic Energy Act.
